Referencing Data to Real-World Locations Using ArcGIS

Displaying real-world features in the right location on a map requires a reference system, and in a GIS, the reference system used is called a coordinate system. This course introduces fundamental concepts of coordinate systems and explains why understanding these concepts is essential to creating accurate GIS maps and reliable analysis results. You will learn guidelines for choosing an appropriate coordinate system and how to change between coordinate systems in ArcGIS.
